gpdf is a GNOME based viewer for Portable Document Format (PDF) files.

Chris Evans discovered several flaws in the way gpdf processes PDF files.
An attacker could construct a carefully crafted PDF file that could cause
gpdf to crash or possibly execute arbitrary code when opened. The Common
Vulnerabilities and Exposures project assigned the names CVE-2005-3624,
CVE-2005-3625, CVE-2005-3626, and CVE-2005-3627 to these issues.

Users of gpdf should upgrade to this updated package, which contains a
backported patch to resolve these issues.
